Many people have type 2 diabetes for years without realising because the early symptoms tend to be general.

Causes of diabetes

The amount of sugar in the blood is controlled by a hormone called insulin, which is produced by the pancreas (a gland behind the stomach).

When food is digested and enters your bloodstream, insulin moves glucose out of the blood and into cells, where it's broken down to produce energy.

However, if you have diabetes, your body is unable to break down glucose into energy. This is because there's either not enough insulin to move the glucose, or the insulin produced does not work properly.

There are no lifestyle changes you can make to lower your risk of type 1 diabetes.

You can help manage type 2 diabetes through healthy eating, regular exercise and achieving a healthy body weight.
